Title: Liquid fuel burner
Inventor: ARAI YASUHIRO
IPC: F23N5/02
Filed: 1988-06-30
Abstract: PURPOSE:To suppress power consumption for heating a vaporizer to a minimum limit and to shorten a rising time up to its ignition by detecting the temperature of primary air around the inlet of a burner, and controlling the temperature of the vaporizer corresponding to the detected temperature. CONSTITUTION:A temperature detector 32 for detecting the temperature of primary air to be sucked into a burner inlet 13 is mounted near the inlet 13, and a controller obtains difference (c) between a present temperature a( deg.C) detected by the detector 32 and a preset reference temperature b( deg.C) (e.g., 10 deg.C). When a room temperature (a) is higher than the temperature (b), the temperature of a vaporizer is set to d( deg.C) (e.g., 260 deg.C). On the other hand, when the temperature (a) is lower than the temperature (b), the temperature of the vaporizer is set to e( deg.C) (e.g., 300 deg.C), and the upper limit temperature of the vaporizer 14 is switched corresponding to the temperature (a). Accordingly, it can prevent the waste of power required to heat the vaporizer 14 including a normal operation time to perform energy conservation, and shorten time required for its ignition.
